Subject: [PATCH 07/16] wl1251: configure hardware en-/decryption for monitor mode
Date: Sat, 26 Oct 2013 22:34:06 +0200 [thread overview]
Message-ID: <1382819655-30430-8-git-send-email-pali.rohar@gmail.com> (raw)
In-Reply-To: <1382819655-30430-1-git-send-email-pali.rohar@gmail.com>
From: David Gnedt <david.gnedt@davizone.at>
Disable hardware encryption (DF_ENCRYPTION_DISABLE) and decryption
(DF_SNIFF_MODE_ENABLE) via wl1251_acx_feature_cfg while monitor interface is
present.
